Title: Decoloring treatment of phosphoric acid produced by wet process
Inventor: FUJII SHIGEO
IPC: C01B25/234
Filed: 1983-11-29
Abstract: PURPOSE:To carry out the decoloring of phosphoric acid produced by wet process, easily, by treating the wet-process phosphoric acid with activated clay under specific condition. CONSTITUTION:Phosphoric acid produced by a wet process is added with 0.1- 5wt% activated clay, and treated at normal temperature -60 deg.C for 10-60min. The phosphoric acid used as the raw material is obtained by treating a phosphorus ore with a mineral acid by hemihydrate process, dihydrate process, or hemihydrate and dihydrate process. When the amount of the activated clay is <0.1%, the decoloring effect is insufficient, ad if it exceeds 5wt%, there is no particular improvement in the effect and accordingly uneconomical. The decoloring effect decreases when the temperature and the treating time are out of the above ranges. The contact of the phosphoric acid with the activated clay can be carried out sufficiently by moderate agitation. After the elapse of the above treating time, the phosphoric acid is separated from the clay by filtration, centrifugal separation, etc. keeping the temperature unchanged.

Title: Wavelength multiplex transmission method using surface light emitting element
Inventor: KAJITA MIKIHIRO
IPC: H04B10/50
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength multiplex transmission method at a low cost by using a surface light emitting element whose device cost is low. SOLUTION: A device is comprised of a surface emission element 1 which emits light of wide spectrum width in each of light emitting parts 2A, 2B, 2C, a plurality of optical fibers 3A, 3B, 3C with different wavelength transmitting regions, a photocoupler 4 which transmits light transmitted through the plurality of optical fibers by photocoupling and transmission optical fiber 5. Lights emitted by the surface emission element 1 of different wavelength regions alone are transmitted by a plurality of optical fibers 3A, 3B, 3C and the lights are coupled and subjected to wavelength multiplex transmission. Therefore, it is not necessary to provide a surface emission element itself with light emission function of different wavelength regions.  Furthermore, it is possible to constitute a monolithic surface emission element, to manufacture it readily and to provide wavelength multiplex transmission which enables information processing of a large volume at a low cost.

Title: Production of continuously cast slab having excellent internal quality
Inventor: AKAISHI GORO
IPC: B22D11/128
Filed: 1993-09-10
Abstract: PURPOSE:To stick the central cavity by pressing and to obtain a continuously cast slab having excellent internal quality without internal crack by continuously casting a low carbon molten steel and executing rolling reduction in a specific condition of the rolling reduction during the unsolidified condition in the center part of the cast slab at the end period of the solidification. CONSTITUTION:Molten steel having $0.18C is continuously cast and one time of the rolling reduction is executed at 2-5% rolling reduction ratio to the part having 90-98% solid phase ratio fS in the center part of the cast slab at the end period of the solidification with rolling reduction rolls having the diameter of 2-5 times of the cast slab thickness. In the case of being <90% the solid phase ratio fS, the internal crack is developed because the solidified shell is weak, and in the case of being >98%, the center cavity is not stuck by pressing because the rolling reduction is not affected to the center. Further, in the case of being >5% the rolling reduction ratio, negative segregation is developed, and in the case of being <2%, the center cavity is not stuck by pressing. Further, in the case of being >=2 the ratio of the roll diameter and the cast slab thickness, the cross sectional area compressive rate and the deformed rate are made to be large and contribute to the sticking of the central cavity by pressing, but in the case of being >=5 this ratio, the bulging in the cast slab between the rolling reduction rolls is developed.

Abstract: PURPOSE:To obtain a superconducting apparatus capable of being safely operated by recovering an evaporated refrigerant from the superconducting apparatus from a ground potential section for a connector for the superconducting apparatus and a normal conductive apparatus, introducing the refrigerant to a liquefying cooler and returning it to the superconducting apparatus again after liquefaction. CONSTITUTION:The inside of a vessel 3 is filled with a refrigerant 5, and the height of an adapter 44 is designed so that a boundary surface between a refrigerant 51 in the liquid phase and a refrigerant 52 in the vapor phase under a normal state during the time of no-load and load is kept within the range of H of the adapter 44. A pipe 6 draws out the refrigerant 52, and introduces it to a liquefier 7, and the refrigerant 5 is liquefied and returned to the vessel 3. The quantity of the refrigerant 52 drawn out is determined by detecting and controlling a level changed with an outside air temperature and load fluctuation by a level gage 8 and a vapor-phase refrigerant pressure gage 9. Consequently, a superconducting apparatus and a normal conductive apparatus can be connected under the state in which no special device is required. Accordingly, the superconducting apparatus capable of being safely operated is acquired.

Title: Seal device
Inventor: YOSHII YASUO
IPC: F02G1/053
Filed: 1987-09-11
Abstract: PURPOSE:To suppress a seal member and portions slidably contacting to the same from wearing and damaging by using a steel member, removed brittle layer after nitriding, in the face which faces to the sliding motion of a seal member. CONSTITUTION:A cylinder 16 is formed of stainless steel finished with lapping, honing or buffing or the like on the surface after nitriding. A seal member 14 with self-lubrication slides as it slidably contacts to the cylinder 16 where brittle layer is removed after nitriding as mentioned above. In this case, no wearing powder is generated from brittle portion and therefore wear loss on the seal member 14 and the cylinder 16 reduces broadly as compared to the case using a conventional cylinder with no finishing after nitriding on the sur face facing to sliding, thereby valve mechanism for suction and exhaust is prevented from acting badly.
